Mike and Meowth were just barely able to evade the Poliwag's attack. Mike agreed with Violet in that he didn't want to fight the Poliwag but rather than confirm with Violet, Mike scooped up Claws and dashed into the mist, using the mist as cover. The two jumped over the small pokemon and dashed for the otherside of the bridge. While running, Mike took out a potion and used it on Claws. Mike then returned Claws back to his Pokeball and used a potion on Venonat. 

Now Mike got to the end of the bridge and dashed towards the angry pinser. 

"Alrighty Pinser. It's high time you put that anger to good use on my team! Go Venonat! Show 'em what your made of!" Mike yelled as he sent Venonat out to fight Pinser. Naturally Venonat was scared but Mike's words of encouragement at least gave her the will to try her best.
